Reaction Steps
A solution of 4-{4-[3-(4-carbamoyl-phenyl)-1H-pyrrolo[2,3-b]pyridin-5-yl]-benzoyl}-piperazine-1-carboxylic acid tert-butyl ester (100 mg, 0.19 mmol) in MeOH (3 ml) was treated with 4 N HCl in dioxane (2.5 ml) and stirred at room temperature for 1 hr. The mixture was evaporated, taken up in MeOH and evaporated again. This was repeated twice to give 102 mg (116%) of the title compound. MS ESI (m/z): MS ESI (m/z): 426.4 (M+1)+, calc. 425.
